Hey Pat, I'm glad you found it useful. My bike is a 2016 also so yours should be doable. My local dealer had no idea what I was talking about until I printed a few pages from the HD service website talking about this. Once they hooked up the digital technician to the bank angle sensor it only took them a few minutes. They didn't find any option for a side car enabled but did find a trike option. Well worth having it done because it sucks having to corner conservatively knowing it will trip on you otherwise.
What website did you find this info on my local Harley attempted to fix this and said it did not work and could not resolve the issue
